资源简介：

This dataset includes four tables with isotopic data and ages for selected igneous bedrock samples collected in 2001 through 2003 from the Western Alaska Range, southcentral Alaska: (1) the concentration of uranium (U) and thorium (Th), ratios of multiple isotopes of lead (Pb) and U, and the age of multiple analytical aliquots, or fractions, of zircon for each sample; (2) the 40Ar/39Ar analytical data and interpreted ages for each rock sample; (3) the sample location, rock characteristics, and interpreted ages for each sample; (4) a data dictionary table, provided as a reference guide for the user.
